Which Heads are better

[mopar madness]

Hay, Guys I have ran up on two sets of heads, need to know which of the two is worth reworking.
Casting numbers 3418915-F
# 4027596-F I'm thinking this set is smog heads from a 360

Thanks

They are pretty much the same. Some 915 heads had 2.02 valves.

If given the choice between a 2.02 head or a 1.88 head I would rebuild the 1.88 head with 2.02 or 2.05 valves. A lot of times rebuilding a original 2.02 head will just sink the valve farther down losing flow. Doing a 1.88 head up will keep the valve up high helping flow and also buying new valves will reduce the head CC. Original 2.02 heads have a large concave to the valve. In my opinion a 1.88 "J" head is worth more than a 2.02 "J" head, unless you go to a 2.05 on it, if this makes any sense!
